Re: our ldm system

Frank,

I'm at the AMS this week.  It's sounds like you had an abnormal stop to
the LDM. I would suggest stopping  the LDM and then doing a :

% ps -eaf | grep ldm

and deleting all the ldm processes.  I believe the other rogue processes
are causing the abnormal situation. Also, you should do an:

% rpcinfo -p

and make sure that port 388 is not being used.

 Yes you can send me your login and
passwd, probably will not get a chance to look at it until FRI.
